What is the Chemical Formula of Zeolite?

Answer: Swedish minerologist Eric Frederik Cronstedt coined the name zeolite in 1756.

He noticed that a rapidly boiling metal (for example Na) which supposed to have stilbite [NaCa4(Si27Al9)O72·28(H2O)] would have produced a huge amount of water vapour that the material would have absorbed.

Due to this phenomenon, he called the material Zeolite (Greek ‘zeo’ means “to boil” and ‘lithos’ means “stone”). Zeolite belongs to the group of microsporous solids and contains a number of little holes (spores).

The general formula of Zeolite stands: MxAlxSi1−xO2·yH2O [here, M is either a metal ion or H+]. Main constituents of Zeolite are Aluminium, Silicon and Oxygen.
